IMPROVEMENT IN CORN-CULTIVATORS.

Specification forming part of Letters Patent No. 16,906, dated March 31,1857.

To all whom it may concern:

Be it known that I, JOHN B. BAKER, of Onondaga, county of Onondaga, inthe State of New York, have invented a new and useful Improvement inOorn-Gultivators; and I do hereby declare that the following is a fulland exact description thereof, reference being had to the accompanyingdrawing, and to the letters of reference marked thereon.

The nature of myinvention consists in constructing the forwardadjusting-bar with circular brace in front or arc, which serves thedouble purpose of brace to said bar and of fender to push the stalksaside without breaking them.

To enable others skilled in the artto make and use my inventioml willproceed to desciibeits construction and operation, reference being hadto the accompanying drawing and the letters marked thereon, of which- Arepresents the main horizontal or center beam; BB. the adjustable sidebeams, which are moved from or toward the center beam at either end onthe adjusting-bars E and G, and secured to the latter by means of boltsb b and D is the rear tooth, the beam or shank of which, F, passes bythe back end of beam A, to which it is tenoned and braced, and issecured to the brace or connecting-rod H of the handles c 0, whichlatter are secured at their lower ends to the main beam A.

D D are the two side or adjustable teeth, which are secured to the beamsB B in the usual way.

E is the circular brace or arc, attached to or formed with the bar E,and bolted to the main beam at e. The object of this circular brace orare is, first, to prevent the adj usting-bar E from being bent or brokenwhen the teeth meet with any obstacle, which disadvantage or accident isconstantly experienced with the plain bars asnow used; and, secondly,this are serves as a fender for readily passing betwen the stalks andlaying aside any which may be in the way without breaking them, as theywould be without said fender or are. It will be seen, then, that soconstructing the adjusting-bar E as that it has an are or fender, E, asdescribed, givesit great advantage in point of durability over those nowin existence, while with little or no extra weight or material themachine is supplied with a guard or fender which lays aside the stalkswhich may be in the way without injuring them.

I operate my cultivator in about the same manner as those now in use.When itis desired to change the distance between the teeth and theirangle with the line of draft the beams B B are adjusted as required uponthe bars E and Grand secured in position by bolts b b and a a.

I am aware thatcultivators have been made with adj usting-bars beforeand behind,whereby the teeth may be adjustedin a manner similar to mine,and I do not therefor wish to be understood as making any claim to theadjust JOHN B. BAKER. [L. s]
